Figure 3. Rankogram for Surgical Site Infection Results.

Figure 3.

The rankogram shows the probability of each preparation option being ranked best performing to worst performing. For example, intravenous antibiotics with oral antibiotics with or without enema (IV + OA ± E) has an 86% probability of being ranked best, 12.7% probability of being ranked second, and a less than 1% probability for the other options. In comparison, IV antibiotics (IV) alone has a 47% probability of being ranked third, 38% probability of being ranked fourth, 12% probability of being ranked fifth, 2.8% probability of being ranked sixth, and less than 1% probability of the other options. IVA indicates adequate IV antibiotics; MBP, mechanical bowel preparation; OA, oral antibiotics.
